Scripps scientists report rare, massive anchovy school

Scientists at the Scripps Institution of Oceanography sighted a massive school of anchovies off the coast of La Jolla, Calif. in early July, according to GrindTv . The school was so large that it appeared to look like an oil slick. Once spotted, oceanography graduate students dived into the waters with a GoPro camera to take video above and below water. They recorded one of the largest schools of anchovies to ever appear so close to shore. Temperature readings near the shore revealed the anchovies were swimming in some of the warmest water they’ve been reported in, 74 degrees. Some of the fish were also collected so that they could be studied, but scientists aren’t sure they’ll ever know why the school appeared so close to shore.

U. of Wash. students estimate Puget Sound sea level rise

Students at the University of Washington have estimated future sea level rise in southern Puget Sound, according to a release from the university. The area is near Olympia, a city particularly prone to rising tides. Using climate models, the students did a case study on shorelines in the region. The models gave them data on ocean temperature and sea-level rise, and historical records helped them put changes that may come into perspective. By 2100, the group found that water near Olympia will rise by 14 to 32 inches and reach levels near that of the open oceans. The students project waters will rise by similar amounts in Seattle.

Future of eDNA could bring easier, low-cost marine species monitoring

Jesse Port imagines a future where fishery managers and conservationists might rely on a few quick water samples to determine great white shark populations or human waterborne pathogens, rather than spending dozens of hours and significant resources on traditional monitoring approaches. An early career fellow at Stanford University’s Center for Ocean Solutions, Port believes the key to this feat is environmental DNA, or eDNA, the genetic information left in an environment by animals. “The approach was well-established prior to this in the world of microbes,” Port said. “It’s been here for a long time… only recently has it been applied to higher organisms: vertebrates, invertebrates, etc.
